Information-bearing article for conveying information which cannot be surreptitiously detected

Claim 2

A pouch formed of a sheet material comprising a polymer-based cohesive seal and said pouch comprising a polymer-based coating formed of small thermoplastic polymeric particles deposited in intimate contact with another within said pouch-forming sheet material, and wherein the appearance of said based coating is irreversibly and substantially changed by subjecting said polymeric particles to temperatures of at least 140° F.

Claim 3

A pouch as defined in claim 1 and comprising at least one organic-solvent-soluble dye coating which will be altered by a broad range of organic solvents.

Claim 4

A secure package resistant to undetectable inspection and formed of a pouch as defined in claim 2 and comprising therewithin articles marked for indicating a winning or losing status in a lottery system.

Claim 5

A secure package resistant to undetectable inspection and formed of a pouch as defined in claim 1 and comprising therewithin articles marked for indicating a winning or losing status in a lottery system.

Claim 6

A sealed pouch as defined in claim 1 formed of two different sheet materials at least one of which comprises a radiation-blocking filler and each of which contains a different dye, one dye being polar and the other dye being non-polar.

Claim 7

A pouch as defined in claim 1 wherein said polymerbased coating is non-reactive to chemicals to which a dye incorporated therewith reacts.

Claim 8

A pouch as defined in claim 1 wherein said pouch comprises a material carrying a radiation-blocking filler.

Claim 9

A secure package resistant to undetectable inspection and formed of a pouch as defined in claim 7 and comprising therewithin articles marked for indicating a winning or losing status in a lottery system.

Claim 10

In a pouch comprising a top sheet and a bottom sheet sealed to form a compartment for holding articles, which are to be maintained from secure non-detectable surveillance, the improvement wherein said bottom sheet and top sheet, taken together contain at least two of the following listed security means in addition to a polymeric coating which irreversibly changes appearance when subjected to temperatures of about 150° F.; (a) a radiation-blocking means in at least one of said top sheet and said bottom sheet (b) a dye which dissolves in polar solvents and (c) a dye which dissolves in non-polar solvents.

Claim 11

In a pouch comprising a top sheet and a bottom sheet sealed to form a compartment for holding articles, which are to be maintained from secure non-detectable surveillance, the improvement wherein said bottom sheet and top sheet, taken together contain at least two of the following listed security means in addition to a polymeric coating which irreversibly changes appearance when subjected to temperatures of about 150° F.; (a) a radiation-blocking means in at least one of said top sheet and said bottom sheet (b) a dye which dissolves in polar solvents and (c) a dye which dissolves in non-polar solvents.

Claim 12

A pouch as defined in claim 9 utilizing all of (a), (b), and (c).

Claim 13

A secure package resistant to undetectable inspection and formed of a pouch as defined in claim 10 and comprising therewithin articles marked for indicating a winning or losing status in a lottery system.

Claim 14

A pouch as defined in claim 9 wherein said polymerbased coating is non-reactive to chemicals to which a dye incorporated therewith reacts.

Claim 15

A sealed pouch formed of at least one sheet material that comprises a polymer based coating formed of small thermoplastic polymeric particles deposited in intimate contact one with another within said pouch-forming sheet material, and wherein the appearance of said polymer-based coating is rapidly and substantially and irreversibly changed by subjecting said polymeric particles to temperatures of 180° F.

Claim 16

A sealed pouch formed of at least one sheet material that comprises a polymer based coating formed of small thermoplastic polymeric particles deposited in intimate contact one with another within said pouch-forming sheet material, and wherein the appearance of said polymer-based coating is rapidly and substantially and irreversibly changed by subjecting said polymeric particles to temperatures of 180° F.

Claim 17

A sealed pouch as defined in claim 13 formed of two different sheet materials at least one of which comprises a radiation-blocking filler and each of which contains a different dye, one dye being polar and the other dye being non-polar.

Claim 18

A pouch as defined in claim 14 wherein said polymer-based coating is non-reactive to chemical to which a dye incorporated therewith reacts.

Claim 19

A pouch as defined in claim 13 wherein said polymer-based coating is non-reactive to chemicals to which a dye incorporated therewith reacts.
